About This File

Create / Test / Learn JSON Processing

jqPlayground is an interactive, jq-based, tool created using AutoIt.  The purpose of the tool is to help in the creation, testing, and understanding of JSON filters/queries used in the  processing of JSON datasets.  Internally, it uses the jq UDF for all JSON processing.  The dot and bracket notation access in jq are similar to other existing AutoIt JSON parsing UDFs and tools.  Therefore, jqPlayground can be used as a general purpose testing & learning tool, regardless of the ultimate UDF or utility you choose to use.  jqPlayground comes with numerous examples to help you see and understand how it can be used for simple parsing and much more advanced JSON processing.  You can modify and play with the example filters or you can create and test your own.


The only requirement needed to run jqPlayground is that it can
find a jq executable.  JQ executables can be found on the JQ
website on the home page, its download section, or as a part
of my JQ UDF in the AutoIt Downloads section.  The latest jq
executables have been included in the zip file.

jqPlayground will look for the jq executable in the following
order of precedence:

1. If a jqPlayground.ini file exists in the script directory, it
   will get the path to the jq executable under to following
   section and key:
   JqExePath=<full path to jq exe>
2. A jq-win32.exe or jq-win64.exe, depending on the OS, in the script directory.

3. A jq.exe in the script directory.


The interface is pretty simple and straight forward.  Paste, load or write
whatever JSON you want to play with in the INPUT section.  Paste or write
whatever parsing or processing filter(s) you want to test in the FILTER
section.  If necessary, you can select or enter any jq-specific flags you
want.  Then, either press the RUN button, F5 or CTRL+ENTER to execute your
filter.  You will see the output in the OUTPUT section.  If your command
was not successful, you will see the error message generated by JQ in the
output section.

There are also numerous examples that can be selected from EXAMPLES
dropdown list.  Upon selecting an example, it populates the filter,
flags, and input as necessary.  It then executes the example, showing
the output in the OUTPUT section.  The examples use one of 2 JSON datasets.
BOOKS is a small, simple, JSON dataset that contains a catalog of book
information.  The NFL JSON dataset is much larger and complex.  It is a
snapshot of NFL game information during week 1 of the 2018 regular season.
Some of the NFL JSON dataset examples really show off the speed and 
processing capabilities of JQ.

If you want to dump the full path of every scalar JSON value in your JSON
dataset, you can type "dump" in the FILTER section and press F5, CTRL+ENTER
or the RUN button.  The output is the same as the jqDump() function in the
jq UDF.  "Dump" is not a jq filter command.  It is a special command that I
added to help those new to JSON understand how to access a given JSON value
using dot-notation.

Lastly, right below the output section, you will see the time it took to
execute your filter.  This can be useful to those in which timimg is a major
